一直对这四者的概念和区别很模糊，现在就特意梳理一下它们的关系与区别。 CGI CGI即通用网关接口(Common Gateway Interface)，是外部应用程序（CGI程序）与Web服务器之间的接口标准，是在CGI程序和Web服务器之间传递信息的规程。CGI规范允许 Web服务器执行外部程序，并将它们的输出发送给Web浏览器，CGI将Web的一组简单的静态超媒体文档变成一个完整的新的交互式媒体。通俗的讲CGI 就像是一座桥，把网页和WEB服务器中的执行程序连接起来，它把HTML接收的指令传递给服务器的执行程序，再把服务器执行程序的结果返还给HTML页。 CGI 的跨平台性能极佳，几乎可以在任何操作系统上实现。 CGI方式在遇到连接请求（用户请求）先要创建cgi的子进程，激活一个CGI进程，然后处理请求，处理完后结束这个子进程。这就是fork- and-execute模式。所以用cgi方式的服务器有多少连接请求就会有多少cgi子进程，子进程反复加载是cgi性能低下的主要原因。当用户请求数量非常多时，会大量挤占系统的资源如内存，CPU时间等，造成效能低下。 CGI脚本工作流程：浏览器通过HTML表单或超链接请求指向一个CGI应用程序的URL。服务器收发到请求。服务器执行所指定的CGI应用程序。 CGI应用程序执行所需要的操作，通常是基于浏览者输入的内容。

问题 Is it possible to disable nginx's custom error pages - if I may call them that - to display my framework's exception pages? I can't really see my werkzeug debugger tool rendered in html...

问题 I have just installed my first uWSGI server on EC2 Ubuntu 14.04 LTS, using the following configuration: [uwsgi] http-socket = :9001 plugin = python wsgi-file = foo.wsgi chdir = /home/bar process = 3 The uWSGI container works fine, but has no logging. Following the manual, I've added the following: logger = file:/tmp/errlog But restarting (using sudo service uwsgi restart ) did not work - the server would not start with this configuration. Any idea what's missing from my ini configuration? 回答1

Websockets in Flask

问题 I'm currently researching websocket support in Python and am a bit confused with the offerings. On one hand it's possible to use Flask + gevent. On the other hand, uwsgi has socket support and at last there is an extension that bundles both uwsgi and gevent. What's the problem with implementing websockets with only one of these? What do I win by mixing them? Changing the question What does adding gevent do that threaded uwsgi won't? 回答1: In regular HTTP requests the connections between client
